For me, the arrival of the winter thrushes from the far north is another one of our great annual events. The BTO has tracked the arrival of fieldfares through its birdtrack scheme and published a graph for the last three years on it web site (click here). This shows a remarkable consistency in arrival dates and numbers. The recent peak in records seems to coincide with my sightings in Durham.
A propos of nothing much.....one of the enjoyable spin-offs of natural history blogging is wandering off down the side alleys that present themselves at random. So, who was Joseph Rock anyway and why the tree named after him? Turns out he was an interesting character who travelled a lot in China collecting plants and taking photos in the early 20th century. The report I found here, says of the Joseph Rock rowan:-
'One of his best-known yet least-documented finds cannot be unequivocally attributed to Rock. It appeared as a chance seedling among Rock’s collections at the Royal Botanic Garden in Edinburgh. No record could be found of an herbarium specimen or field note, and some even believe it to be a hybrid.'
So there you have it.
